Yeah, that does stink. :/ But the reason for the wait is probably because your case is considered low priority. Because it's so much more likely just IBS, and by the time that appointment comes you'll be feeling better anyway.

Ah, sorry, I don't live in Ireland so I guess I'm not familiar with how that works. Either way though it's really very likely you'll be fine, and that something on your tailbone is not cancer. Keep us updated.
